Viruses vary in the makeup of their genetic material. Some have double-stranded DNA, but other viruses have genomes composed of single-stranded DNA, double-stranded RNA, or single-stranded RNA. Single-stranded molecules have a single polymer of DNA or RNA that does not form a double-helix and does not base-pair with a complementary polymer. What predictions could you make about base composition in the genomes of these organisms?

    ii) Viruses are classified mainly on the basis of their nucleic acid genomes. The genome can consist of single or double stranded DNA or single or double stranded RNA.

  • Viral Replication - Six Events

    Circular DNA (so-called "normal " viruses), both double-stranded and single-stranded is replicated using a "rolling circle " mechanism. In it, the circular genome is transcribed over and over again along the circumference of the circle.

    Therefore the virus can spread very widely, causing a global pandemic such as that seen in the 2009 H1N1 influenza pandemic. Reassortment can also occur with the reoviruses, such as rotavirus, which are multipartite double stranded RNA viruses.
